Using R and Quarto via RStudio IDE (Ismay & Kim, 2020, Chapter 1)
Installing the tidyverse as an example
Copy and paste this code in the console. If you have already installed the tidyverse nothing will happen but if you don’t have installed the tidyverse then the package is going to be installed
Installing a package is like downloading an app from a store where you need to do it only once
Loading a package
